Description

Technical Field

[0001] The utility model relates to the field of plastic pipe processing, in particular to a plastic pipe hot-melting device. Background Art

[0002] Plastic pipes have been widely used in construction projects due to their light weight, corrosion resistance, beautiful appearance, easy processing and convenient construction. Plastic pipes are mainly divided into two categories: thermoplastic plastic pipes and thermosetting plastic pipes. Thermoplastic plastic pipes can be softened and reshaped after heating, while thermosetting plastic pipes cannot be reshaped by heating after being heated and cured.

[0003] Hot melt connection is an important method for connecting plastic pipes, mainly suitable for thermoplastic plastic pipes. Hot melt connection mainly uses a hot melt tool to heat the cross-section of the pipe and fittings to a molten state at the same time, and then butt-extrude them to form a reliable connection.

[0004] Existing plastic pipe hot-melt connections usually use bolt clips to fix the plastic pipes. During production and observation, it was found that the fixing device needs to be replaced when fixing plastic pipes of different sizes, which makes the processing steps of plastic pipe hot-melt more cumbersome and increases the working time required for plastic pipe hot-melt.

[0005] Therefore, a plastic pipe hot-melting device is proposed in response to the above problems. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0008] Preferably, a plurality of fixing holes are provided in the middle of the top plate; a spring is fixed to the inner side wall of the fixing hole; a sliding rod is fixed to the end of the spring; the sliding rod and the fixing hole are slidably connected; through the cooperation of the sliding rod and the spring, the speed of the plastic tube when falling is slowed down, and the impact generated when the plastic tube and the top plate contact is reduced, while also increasing the contact area between the device and the plastic tube, thereby improving the stability of the device in fixing the plastic tube.

[0009] Preferably, a pressure plate is fixed to the end of the sliding rod; the pressure plate is an arc-shaped structure; when the sliding rod comes into contact with the plastic tube, the pressure plate will also come into contact with the plastic tube. Because the pressure plate is an arc-shaped structure, the pressure plate will fit more closely with the inner wall of the plastic tube, increasing the contact area between the sliding rod and the plastic tube, and further enhancing the stability of the device in fixing the plastic tube during hot melting.

[0010] Preferably, a plurality of friction pads are fixedly connected to the middle part of the pressure plate; the surface of the friction pad is grooved; when the pressure plate contacts the inner wall of the plastic tube, the friction pad will also contact the plastic tube. Because the friction coefficient of the friction pad surface is larger, the friction pad will increase the friction between the pressure plate and the plastic tube, further reducing the shaking that occurs during the hot melting process of the plastic tube, and improving the stability of the device in hot melting the plastic tube.

[0011] Preferably, a plurality of elastic rods are fixedly connected between adjacent top plates; the elastic rods are located between the elastic cloth and the connecting plate; under normal conditions, the elastic rods are in a bent state, and the elastic rods will squeeze the elastic cloth so that the elastic cloth is kept as tight as possible, thereby increasing the contact area between the elastic cloth and the plastic tube and enhancing the fixing effect of the device on the plastic tube.

[0012] Preferably, a plurality of cleaning rods are fixedly connected to the middle of the elastic rod; a plurality of circular holes are opened in the middle of the elastic cloth; adjacent cleaning rods are located inside the circular holes; when the plastic tube slides along the top plate, the plastic tube will come into contact with the circular holes, and the circular holes will clean the impurities attached to the inner wall of the plastic tube, thereby realizing the cleaning effect of the device on the plastic tube and reducing the impurities attached to the inner wall of the plastic tube.

[0013] Preferably, a plurality of collection boxes are fixedly connected to the top of the workbench; the collection boxes are located between a pair of slides; when the slides slide along the workbench, dust and other impurities attached to the surface of the workbench are removed, and these impurities will eventually be gathered inside or around the collection boxes, and finally the staff can collect and process these impurities.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Specific examples are given below.

[0026] See also Figures 1 to 5 As shown, a plastic pipe hot-melting device according to an embodiment of the present invention comprises a workbench 1; a motor 12 is fixedly connected to the middle of the workbench 1; a forward and reverse screw 13 is fixedly connected to the output end of the motor 12; a slide 14 is symmetrically threadedly connected to the middle of the forward and reverse screw 13; the slide 14 and the workbench 1 are in sliding connection; a cylinder 15 is fixedly connected to the middle of the slide 14; a connecting plate 16 is fixedly connected to the output end of the cylinder 15; the slide 14 is located between the cylinder 15 and the connecting plate 16; a plurality of connecting rods 18 are hinged to the middle of the connecting plate 16; the ends of the connecting rods 18 are hinged to the ends of the connecting rods 18. The top of the workbench 1 is hinged with a slider 17; the slider 17 and the slide 14 are slidably connected; the middle of the slider 17 is fixed with a top plate 19; elastic cloth 110 is fixed between adjacent top plates 19; a power assembly 111 is provided on the top of the workbench 1; a heating plate 112 is installed in the middle of the power assembly 111; when working, two plastic tubes can be respectively sleeved on the surface of the top plate 19, and then the cylinder 15 can be started to make the connecting plate 16 close to the slide 14. When the connecting plate 16 moves, the angle of the connecting rod 18 will change, and the slider 17 will move along the hinged action of the connecting rod 18. As the slide plate 14 slides, the slider 17 will move away from the connecting plate 16 and drive the top plate 19 to move together, and the elastic cloth 110 will move together with the top plate 19 until the top plate 19 and the elastic cloth 110 are close to the inner wall of the plastic tube. At this time, the device fixes the plastic tube, and then the motor 12 can be started to rotate the forward and reverse screws 13. When the forward and reverse screws 13 rotate, the pair of slide plates 14 will approach each other. When the slide plate 14 moves, it will move the plastic tube together. At the same time, the heating plate 112 will also slide along the power component 111 and be at the same height as the plastic tube. Finally, the end of the plastic tube The top plate 19 and the elastic cloth 110 will move closer to the inner wall of the plastic tube as the slider 17 is hinged to the connecting rod 18, thereby realizing the fixation of plastic tubes of different sizes during hot melting, improving the flexibility and adaptability of the device for fixing plastic tubes of different sizes and multiple models during hot melting, and shortening the working time required for the device to fix plastic tubes of multiple sizes.

[0027] See also Figures 3 to 5 As shown, a plurality of fixing holes 2 are opened in the middle of the top plate 19; a spring 22 is fixed to the inner side wall of the fixing hole 2; a sliding rod 23 is fixed to the end of the spring 22; the sliding rod 23 and the fixing hole 2 are slidably connected; when the plastic tube is placed on the surface of the top plate 19, the sliding rod 23 is squeezed, and the sliding rod 23 slides along the fixing hole 2 after being squeezed by the plastic tube, reducing the direct contact between the plastic tube and the top plate 19 when placed. At the same time, the spring 22 will also be in a compressed state. When the top plate 19 and the elastic cloth 110 fit the plastic tube, the sliding rod 23 will squeeze the inner wall of the plastic tube under the elastic force of the spring 22; through the cooperation of the sliding rod 23 and the spring 22, the speed of the plastic tube when falling is slowed down, and the impact generated when the plastic tube and the top plate 19 contact is reduced. At the same time, the contact area between the device and the plastic tube is increased, and the stability of the device in fixing the plastic tube is improved.

[0028] See also Figure 5 As shown, the end of the slide rod 23 is fixedly connected with a pressure plate 3; the pressure plate 3 is an arc-shaped structure; when the slide rod 23 comes into contact with the plastic tube, the pressure plate 3 will also come into contact with the plastic tube. Because the pressure plate 3 is an arc-shaped structure, the pressure plate 3 will fit more closely with the inner wall of the plastic tube, increasing the contact area between the slide rod 23 and the plastic tube, and further enhancing the stability of the device in fixing the plastic tube during hot melting.

[0029] See also Figure 5 As shown, a plurality of friction pads 4 are fixedly connected to the middle of the pressing plate 3; the surface of the friction pad 4 is grooved; when the pressing plate 3 contacts the inner wall of the plastic tube, the friction pad 4 will also contact the plastic tube. Since the surface friction coefficient of the friction pad 4 is larger, the friction pad 4 will increase the friction between the pressing plate 3 and the plastic tube, further reducing the shaking during the hot melting process of the plastic tube and improving the stability of the device in hot melting the plastic tube.

[0030] See also Figure 3 and Figure 4 As shown, a plurality of elastic rods 5 are fixedly connected between adjacent top plates 19; the elastic rods 5 are located between the elastic cloth 110 and the connecting plate 16; in a normal state, the elastic rods 5 are in a bent state, and the elastic rods 5 squeeze the elastic cloth 110 so that the elastic cloth 110 remains as tight as possible, thereby increasing the contact area between the elastic cloth 110 and the plastic tube and enhancing the fixing effect of the device on the plastic tube.

[0031] See also Figure 4As shown, a plurality of cleaning rods 6 are fixedly connected to the middle of the elastic rod 5; a plurality of circular holes 62 are opened in the middle of the elastic cloth 110; adjacent cleaning rods 6 are located inside the circular holes 62; when the plastic tube slides along the top plate 19, the plastic tube will come into contact with the circular holes 62, and the circular holes 62 will clean the impurities attached to the inner wall of the plastic tube, thereby realizing the cleaning effect of the device on the plastic tube and reducing the impurities attached to the inner wall of the plastic tube.

[0032] See also Figure 1 As shown, a plurality of collection boxes 7 are fixedly connected to the top of the workbench 1; the collection boxes 7 are located between a pair of slides 14; when the slides 14 slide along the workbench 1, dust and other impurities attached to the surface of the workbench 1 are removed, and these impurities will eventually be gathered inside or around the collection boxes 7, and finally the staff can collect and process these impurities.

[0033] Working principle: The two plastic tubes can be respectively sleeved on the surface of the top plate 19, and then the cylinder 15 can be started to make the connecting plate 16 approach the slide 14. When the connecting plate 16 moves, the angle of the connecting rod 18 will change, and the slider 17 will slide along the slide 14 under the hinge action of the connecting rod 18. At this time, the slider 17 will move away from the connecting plate 16 and drive the top plate 19 to move together. The elastic cloth 110 will move with the top plate 19 until the top plate 19 and the elastic cloth 110 are close to the inner wall of the plastic tube. At this time, the device fixes the plastic tube, and then the motor 12 can be started to rotate the forward and reverse screws 13. When the plastic tube is placed on the surface of the top plate 19, the sliding rod 23 is squeezed, and the sliding rod 23 is squeezed by the plastic tube and slides along the fixing hole 2, reducing the amount of plastic tube placed. When the slide bar 23 is in contact with the plastic tube, the pressure plate 3 will also be in contact with the plastic tube. Because the pressure plate 3 is an arc-shaped structure, the pressure plate 3 will be more in contact with the inner wall of the plastic tube, increasing the contact area between the slide bar 23 and the plastic tube. When the pressure plate 3 is in contact with the inner wall of the plastic tube, the friction pad 4 will also be in contact with the plastic tube. Because the surface friction coefficient of the friction pad 4 is larger, the friction pad 4 will increase the friction between the pressure plate 3 and the plastic tube. The elastic rod 5 is in a bent state in a normal state, and the elastic rod 5 will squeeze the elastic cloth 110 so that the elastic cloth 110 is kept as tight as possible, thereby increasing the contact area between the elastic cloth 110 and the plastic tube. When the plastic tube slides along the top plate 19, the plastic tube will come into contact with the circular hole 62, and the circular hole 62 will clean the impurities attached to the inner wall of the plastic tube, thereby realizing the cleaning effect of the device on the plastic tube. When the slide plate 14 slides along the workbench 1, it will remove impurities such as dust attached to the surface of the workbench 1, and these impurities will eventually be collected inside or around the collection box 7.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
